<td align="left" headers="r2c1-t26 r1c2-t26">If selected, the IDE uses its internal diff engine. When using the internal diff engine, you can let the engine ignore white spaces and changes in case. The former option is selected by default.</td>

<p>External Diff</p>
</td>
<td align="left" headers="r3c1-t26 r1c2-t26">If selected, the IDE uses an external command-line diff executable. You can specify any diff command options (for example, <code dir="ltr">diff -b</code>) to be used when running the diff command from a command-line executable in the IDE. Diff options are not availabe when using the built-in diff engine.
<p>To use this option, you must have a command-line diff executable installed on your system if you want to compare revisions.</p>
